PC giant Hewlett-Packard (NYSE:HPQ) reports earnings tomorrow, and there's a lot for investors to watch for. Shares have been rallying ever since Hewlett-Packard hosted its analyst meeting last month and offered reassuring guidance for fiscal 2014. The consensus estimates call for nearly $28 billion in revenue and $1 in earnings per share this quarter.

CEO Meg Whitman has acknowledged the many challenges HP faces going forward and believes that 2014 will be the company's pivotal year. Results from printing peers suggest that Hewlett-Packard's printing business may face headwinds. Investors may also look for clues on how Project Moonshot is faring in the data center, while HP could also be losing share in enterprise storage to NetApp and EMC.
